Kukiya maxillofacial plateszvigadziriso zvekutyoka zvinoshandisa chinokiyiwa kuti ubate screws nema plates pamwechete.Izvi zvinopa kuwedzera kugadzikana uye kusimba kune pfupa rakatyoka, kunyanya mumatambudziko akaoma uye comminuted fractures.
Zvichienderana nekugadzirwa kwegadziriro yekuvhara, kukiya maxillofacial mahwendefa anogona kukamurwa kuva maviri makuru marudzi: threaded yekuvhara mahwendefa uye tapered yekuvhara mahwendefa.
Pane shinda dzinoenderana pamisoro yescrew uye maburi maburi eshinda yekukiya ndiro.Matanidza saizi nechimiro chescrew head neburi replate, wosunga sikuruu kusvika yakiiwa nendiro.Izvi zvinogadzira chimiro chakamisikidzwa chinodzivirira screws kubva pakusunungura kana kukona.
Misoro yescrew uye maburi eplate ematapered locking plates ane conical shape.Misoro ye screw uye maburi ebhodhi akati siyanei saizi uye maumbirwo, isa siruu kusvika yabatanidzwa nebhodhi.Izvi zvinogadzira friction inobata sikuruu nendiro pamwechete.
Mhando mbiri dzekuvhara maxillofacial platesvane zvazvakanakira nezvazvakaipira.Mahwendefa ekukiya ane shinda anobvumira kurongeka chaiko kwemasiruu nendiro, asi zvinoda nguva yakawanda nehunyanzvi kuti uise masiruu mukati chaimo pakati pemaburi eplate.Tapered locking plates inobvumira kuchinjika kukuru uye nyore kuisa screw, asi inogona kukonzera kushushikana kukuru uye deformation yeplate.
Kukiya maxillofacial mahwendefa zvakare anouya akasiyana maumbirwo uye saizi zvichienderana nenzvimbo uye kuoma kwekutsemuka.Mamwe maumbirwo akajairika ekukiya shaya mapaneru ndeaya:
Ndiro yakatwasuka: inoshandiswa kune yakapfava, mitsetse yakatsemuka senge symphysis uye parasymphysis fractures.
Kubhenda ndiro: inoshandiswa kune akakombama uye angular fractures, senge angular fractures uye kutsemuka kwemuviri.
L-yakaita ndiro: inoshandiswa kune angular uye oblique fractures, yakadai seramus uye condylar fractures.
T-sheped steel plate: inoshandiswa kune T-shepe uye bifurcated fractures, senge alveolar bone uye zygomatic bone fractures.
Ndiro yesimbi yakaita seY: inoshandiswa kuita Y-yakaita uye yakatsemuka katatu, senge orbital uye nasal orbital fractures.
Mesh ndiro: inoshandiswa kune zvisina kujairika uye comminuted fractures, senge huma uye temporal fractures.
Kukiya maxillofacial ndirotekinoroji yepamusoro uye inoshanda yekurapa maxillofacial fractures.Inopa kugadzikana kuri nani, kuporesa uye aesthetics pane zvechinyakare zvisiri zvekukiya mahwendefa.Zvisinei, inodawo humwe unyanzvi, zvigadzirwa uye mari kudarika mahwendefa asina kuvhara.Saka, kusarudzwa kwekuvhara maxillofacial plates kunofanira kubva pane zvinodiwa nemunhu uye zvido zvemurwere uye chiremba anovhiya.
